In this description, called the nebular model, our sun coalesced first, surrounded by a spinning disk of gas and dust. How the sun formed Some evidence, such as a 2010 study from scientists at the Carnegie institution, suggests this contraction could have been spurred by a burst from nearby supernovas . Other forces like differences in density could also have caused the cloud begin collapsing according to "From Suns to Life: A Chronological Approach to the History of Life on Earth" (Springer, 2004), an astronomy review text. Initially, gas collected in the dense center of this spinning disk, creating a protosun. How the planets formed Meanwhile, in the disk of material around the young sun, a process called accretion formed the planets, moons, comets and asteroids. Got a question?

Nikola Tesla: The Genius Who Lit the World This is the documentary film about Nikola Tesla, the scientist and inventor, one of the greatest men in history. Nikola Tesla was born on July 10,1856 in Smiljan, Lika in what later became Yugoslavia. His father, Milutin Tesla was a Serbian orthodox priest and his mother Djuka Mandic was an inventor in her own right of household appliances. Tesla studied at the Polytechnic Institute in Graz, Austria and the University of Prague. Before going to America, Tesla joined Continental Edison Company in Paris where he designed dynamos. Young Nikola Tesla came to the United States in 1884. Direct current flows continuously in one direction; alternating current changes direction 50 or 60 times per second, and can be stepped up to very high voltage levels, minimizing power loss across great distances. Tesla's A-C induction motor is widely used throughout the world in industry and household appliances. Watch the full documentary now
Democratic Party (United States) Since the 1930s, the party has promoted a social liberal platform.[2][11][12] Until the late 20th century the party had a powerful conservative and populist wing based in the rural South, which over time has greatly diminished. Today its Congressional caucus is composed mostly of progressives and centrists.[13] History The Democratic Party evolved from the Jeffersonian Republican or Democratic-Republican Party organized by Thomas Jefferson and James Madison in opposition to the Federalist party of Alexander Hamilton and John Adams. 1860s 1900s Agrarian Democrats demanding Free Silver overthrew the Bourbon Democrats in 1896 and nominated William Jennings Bryan for the presidency (a nomination repeated by Democrats in 1900 and 1908).
